You got binary compatible packages for all purposes. I make school-alike server with many features you are requested, but now it lacks of internationalization, all interface on russian. It now has DHCP+DNS with dynamic updates, central LDAP authentication for Samba, Apache, Squid, Sendmail and Dovecot, virus filtering with ClamAV on Squid and Sendmail (through c-icap and milter), spam protection with black and greylisting, internet usage accounting and managing and more. You can see source on our site: http://www.abbris.ru/officemaster May be it's not so pretty code yet, but it written by administrator for non-it-aware people and those who use it like it. You can see some screenshots on our site (http://www.abbris.ru), but, sorry all in russian. You can help us to make it better and localize it to other languages if you want. All code is GPL licensed and will be available on sf.net soon. With best regards, Sergey.
